2009-03-16zd1211rw: Do not panic on device eject when associatedJouni Malinen
zd_op_tx() must not return an arbitrary error value since that can leave mac80211 trying to retransmit the frame and with the extra data pushed into the beginning of the skb on every attempt, this will end up causing a kernel panic (skb_under_panic from skb_push call). This can happen, e.g., when ejecting the device when associated. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-03-16ath9k: implement IO serializationLuis R. Rodriguez
All 802.11n PCI devices (Cardbus, PCI, mini-PCI) require serialization of IO when on non-uniprocessor systems. PCI express devices not not require this. This should fix our only last standing open ath9k kernel.org bugzilla bug report: http://bugzilla.kernel.org/show_bug.cgi?id=12110 A port is probably required to older kernels and I can work on that.

2009-03-13mv643xx_eth: fix unicast address filter corruption on mtu changeLennert Buytenhek
When mv643xx_eth_open() is called to up an interface, port_start() will first re-program the unicast address filter, and then re-initialise the PORT_CONFIG register, but that will disable unicast promiscuous mode if it was enabled by the unicast address filter setup. This isn't a problem on ifconfig up, as ->set_rx_mode() will be called shortly afterwards which will program the filters again, but it does trigger when changing the MTU, which calls mv643xx_eth_stop() and then mv643xx_eth_open() by hand to repopulate the receive rings with skbuffs of the new size. Swap the initialisation of the PORT_START register and the call to the unicast filter setup function to fix this. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: David S.

Ericsson has provided a "class" driver for this device: http://kerneltrap.org/mailarchive/linux-net/2008/10/28/3832094 But closer inspection of that driver reveals that it adds little more than duplication of code from cdc_ether.c.

2009-03-01r8169: read MAC address from EEPROM on init (2nd attempt)Ivan Vecera
This is 2nd attempt to implement the initialization/reading of MAC address from EEPROM. The first used PCI's VPD and there were some problems, some devices are not able to read EEPROM content by VPD. The 2nd one uses direct access to EEPROM through bit-banging interface and my testing results seem to be much better. I tested 5 systems each with different Realtek NICs and I didn't find any problem. AFAIK Francois's NICs also works fine. Original description: This fixes the problem when MAC address is set by ifconfig or by ip link commands and this address is stored in the device after reboot. The power-off is needed to get right MAC address. This is problem when Xen daemon is running because it renames the device name from ethX to pethX and sets its MAC address to FE:FF:FF:FF:FF:FF. After reboot the device is still using FE:FF:FF:FF:FF:FF. Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-02-25Fix iwlan DMA mapping directionFenghua Yu
When iwlan runs on IOMMU, IOMMU generates a lot of PTE write faults because PTE write bit is not set on some of PTE's. This is because iwlan driver calls DMA mapping with PCI_DMA_TODEVICE which is read only in mapping PTE. But iwlan device actually writes to the mapped page to update its contents. This issue is not exposed in swiotlb. But VT-d hardware can capture this fault and stop the fault transaction. The following patch fixes the issue.
